Treatment Comparison

	Closure® Procedure	Vein Stripping and Ligation	Endovenous Laser (EVL)
Typical Results 48 Hours After Procedure
Proven Advantages over Vein Stripping in Randomized Comparative Trial	Quicker return to normal activities, less pain, bruising, and discomfort during early recovery	N/A	No randomized comparative trial reported
Absence of Varicose Veins at 12 Months	90% of legs treated	85% of legs treated	This type of outcome not reported
Return to Normal Activities within 24 Hours	89.1% of patients	(Not reported)	69.8% of patients
Method of Action	RF energy delivered directly to the vein wall removes the vein wall lining and induces collagen contraction. Fibrosis of treated vein continues for months. By 6-12 months post-op, the fibrosed vein may be resorbed and become sonographically invisible.		Laser energy boils the blood. A laser-induced steam bubble heats residual blood in the treatment vein producing thrombotic occlusion.
Post-op Bruising	4%	N/A	38%
Patient Satisfaction	98% of patients surveyed would recommend to a friend	(Not reported)
Intraoperative Physician Feedback	Physicians receive real-time feedback during the procedure on key treatment parameters.	N/A	EVL systems have no intraoperative feedback systems.
